    My Goliathus Goliatus Video Logs

    Awesome video!
  4. Hey guys! I started a YouTube series to document my breeding of Goliathus goliatus. I hope to generate more discussion around these guys and get expand the breeding. Check it out!
  5. it depends. the most extreme case in Dynastes beetles was between D. hercules and D. neptunus. see the link below: http://insectforum.no-ip.org/gods/cgi-bin/topic.cgi?forum=2&topic=20521 the same progeny successfully produced F2 and F3. That is, the hybrid offspring are viable and also fertile. However, the viability did decrease, where many larvae died soon after hatching. If you are friend with the breeder in Facebook, you can find the image of the F1, F2, and F3 adults from the link: I am breeding D. maya x D. grantii in my lab. the idea is to create F1 and F2 offspring and use them for associate mapping to figure out the genes associated with different body coloration. So far the egg production is nice, but will need more time to find out if they hatch and the percentage of larvae that can reach adulthood.
  6. Very lucid explanation; thanks much!
  7. To provide an explanation what I replied to this original quthor: One of the definition for biological species is an ability to continuously breed, which means, it has to be fertile throughout the generations. There are some words that Dynastes grantii and D. tityus can hybridize, but there is only one generation comes out of it, no officially known F2 specimens exist. Only hybridization data available is from U of Kentucky, but they got males only for the F1 Hybrids, and there is no further records about it. Sister species are close to each other, so they may be able to mate and breed for only one generation because that hybrid generation is lacking fertility. There were some ads for dried specimens of [ D. hercules X D. hyllus ] and [ D. hercules X D. grantii ] couple times a while ago in Japanese auctions, but that is very rare case, and never heard of any further generations occurred. Ultimately, back to the original question: Is it possible to mate? yes, the copulation can occur, but genitalia may not perfectly fit in. To have a perfect and proper copulation to occur, a male genitalia must be properly inserted into a female genitalia. Genitalia of male and female of same species work like a key to a lock. (which is why morphological characteristic of genitalia can be a great key to identify species) Even if the copulation occurs, their genes are differ, and may not properly fertilize. And also, as I mentioned above, the hybrid generations are not fertile to produce next generations. (they sometime don't even have a genitalia to copulate).
  8. Translation please! Inquiring minds -- and my pet beetles -- want to know! ๐Ÿ˜‰
  9. My last correspondence with Bill Wallin was 7 years ago (June 2012). Surely though, he was not the only one to have ever produced tityus X granti hybrids? In any case, please always be careful to keep hybrids separated from pure species cultures.
  10. For everyone who already has read this article, and wonders about what happened afterward: Unfortunately, according to UKY ento dept. personnel, there has been no update to this article (and the study) because the one who conducted this study is no longer affiliated to UKY, and the department has no contact info whatsoever of the person (which sounds weird). They have no clue whether the hybrid F1 was fertile and had an ability to breed any further generations. I contacted UKY personnel to know the further updates while I was working on a manuscript, to be published, of the occurrence of Dynastes tityus (L.) in Louisiana.

  12. Thank you for sharing this insight. I have some knowledge regarding this topic, but you connect each point very well.

    Carnivorous Plants

    Yes, you are right. I was wrong about the soil part.. I only knew that they don't consume bugs trapped as the main source of nutrition, and since I was aware they require full sunlight, I thought sunlight AND SOIL is what they mainly absorb nutrition from. I found this out far later, couple months ago, when I found some Drosera brevifolia on my backyard. They were growing on sand, so I noticed they barely get any nutrition from soil.

    Hate to call you out on this but CPs do best in low/no nutrient soils. In fact, soils with too many nutrients/minerals/salts will kill the plant. You are correct that they require sunlight - in fact, most CPs require HIGH intensity light (full sun or extremely bright artificial lighting - I use both). Some CP species such as nepenthes can tolerate lower levels of light but something like a sundew, american pitcher plant, or VFT requires high levels of light to grow well. While most CPs can tolerate extended periods without feeding, you will get the best growth with regular infrequent feeding. For example, feed your pitcher plants every 2-4 weeks but not with every watering. Do not fertilize the soil. You can introduce insects to the pitchers or traps. Like the soil, the water used must be pure and nutrient-free so a TDS of <50ppm is preferred. The closer you get to 0ppm TDS, the better.

    Congratulations on this; the updates are fascinating and very informative. Best wishes for the whole amazing family!

    Hello from Georgia! (USA)

    Hello TityusAndronicus, I am from Georgia too and I have some Tityus if you want to stop by and take a look let me know.

    Baby rhino roaches!

    Some more photos of the growing little roaches! I bothered them to count babies again today - all sixteen are still happy and healthy and most of them look like they're about to molt again. I recently got a photo of one of them barely out of the old exoskeleton. Later this month I'm going to begin transferring the babies to their own container, probably a few at a time to avoid stressing out the mother with a suddenly empty nest. She's been doing such a great job of raising her little ones.

    Can Alphitobius diaperinus fly?

    Thank you Ratmosphere, I don't think they can fly either. I spent a lot of time watching them and there was no flying. I must have a freeloader. Take care, Koyle

    Can Alphitobius diaperinus fly?

    I don't think they could fly.
  25. Hello, I would like to know if Alphitobius diaperinus can fly? I am raising some for the first time and now I am seeing very small beetles in my enclosure. Almost seems they are actually to small to be juvenile Alphitobius diaperinus. Any thoughts? Thank you

    Thereโ€™s other typos as well, this forum is not letting me attach more pics. Oh well.

    GIRL Skateboards Typo

    GIRL is the skateboard company name. Canโ€™t really blame em, but if youโ€™re gonna be putting this idea out you might as well do the research first. Sick skateboards and concept, just wish the beetles were identified right! Woulda bought the whole series lol.
